GameStop said chief executive George Sherman will step down by 31 July, the latest in a series of changes to the video-game retailer’s leadership team since Chewy co-founder Ryan Cohen became a board member in January.

Cohen, who has been nominated as GameStop’s chairman, had urged the company to focus on e-commerce and reduce store count, among other initiatives. The company is now working to transform its decades-old bricks-and-mortar business to become more technology-centric.
